AOCJY3-12.800MHZ-F Application Field and Working Principle

Oscillators are extremely important components in any electronic system and play a major role in maintaining correct timing and defining digital signals. The AOCJY3-12.800MHZ-F oscillator, used in a variety of applications, is a miniature case ceramic surface mount designed to allow the center frequency to be adjusted within a defined tuning range.

The device is part of a Class 1 ceramic circuit and is projected to be in compliance with latest JEDEC standards. It is designed to provide a high degree of stability over a wide temperature range and high shock and vibration requirements. The AOCJY3-12.800MHZ-F oscillator is a RoHS compliant product.

Working Principle

The oscillator is designed around an IC, the oscillation frequency is determined by a resonator quartz crystal at the center of the oscillator. Two capacitors are typically connected to the crystal to provide a stable output. The quartz crystal is controlled by the IC and is operated within an allowable tuning range.

The AOCJY3-12.800MHZ-F oscillator is designed to power itself by the input signal, that is, when the IC senses a voltage change greater than a threshold voltage the signal is echoed out by the IC and powers the quartz crystal. The frequency is defined by the resonant frequency of the quartz crystal. The current draw is highly dependent on the signal frequency and the application circuit in which the oscillator is used.

Applications

The oscillator is suitable for a variety of applications including audio-visual equipment, communication devices, gaming systems, PCs, VoIP phones, and more. It can be used in analog and digital circuits with equal success. As a chip, it can be used to create tracking dependencies for both high and low frequency clock tasks. Additionally, its low power consumption make it well-suited for battery-operated equipment.

Due to its small size and high performance, the device is useful in remote application, where size and weight are a premium. Its ability to maintain its frequency in high shock and vibration environments, make it ideal for automotive, aerospace and military applications.
